cry02 cooling

[BeRad]

ive been having a dig around the online performance shops of late looking for engine internals and the like, when i came across an cryo2 cooling system, which looks to be similar to n2o if not an identical concept, so my question is would one of these systems be legal to use on the street and has anyone used one to know what benefits would be had?

I guess it wouldnt be legal due to the possibility of large power gains at the press of a button.

heres an example of the kit.

More info on the Cry02 system, these guys either use a lot of it or actually make the equipment. Not sure about the road worthiness of it though

-requires large amount of CO2 for continuous use
-large bottle of (inert) gas with potential for explosion during a fire
-large bottle of gas that contents of could smother occupants of car if major leak went un-noticed
-no dye or odour indicator to show leakage

As it's only useful for drag racing, you'd be better off with a water spray on the intercooler (much cheaper) for regularly use and a 2nd cooler in an ice bath for racing use only?

With these kits, the CO2 isn't actually put into the engine like nitrous.

Nitrous is actually cheaper, and probably more effective.

Ok just a thought thanks guys.

[OnAll-FOUR]

Do you know what a setup would cost? what is the price of CO2 vs Nos?

Probably isn't really road practical as you have to keep a good supply of CO2 but for a blast at the drags or a dyno king it may be useful.

The idea sounds like a sensible one, use the vapor change process to cool the intake, and fuel rail, and then dump it out on the intercooler.

If the price/gain is reasonable then I wouldn't discount it

Cheers

prices are around the same between n20 and co2 depends what addons you get for each kit which makes them more expensive.

My mate ran co2 on his stock side mount cooler on his GTS R31 Skyline. He said it made a world of difference on 16psi, the pickup and no loss of torque or power towards the top end. I don't have any ideas on power outputs or anything, but he simply had sprayers which froze his cooler.

in such a under performing setup up like the skyline I/C it prob would make a massive difference! but on a decent sized I/C which is able to keep air temps fairly stable on its own the gain would not be as big but still there..

Having the cryo spray in drag use and dyno comps would be a bonus but then you can just use raw nitro's
i can vouch for the massive amount of difference that shit makes!

I have this system at the moment. I am yet to test it on the dyno... I made a tread about it ages ago. It will make difference because it will drop the temperatures further down then the intercooler can. This is especially true if you drive an automatic and stall off the line. Building boost while standing still will heat sink the cooler before you take off. The biggest difference will be seen on the dyno where there is a lack of airflow. The intercooler spray is the only one worth it. If you thinking of getting this system just rent a c02 bottle from supagas, or a welding joint and make the kit your self. You might have troubles finding someone to fill the cry02 branded bottle. I will post results here after my dyno.
I got the kit cause the smallish hiflo ct12's produce a bit of heat at 18psi unlike more efficient turbos, do not have a massive size front mount and due to the above reason of heat sinking the cooler while stalling of the line. So for me it worked a treat. Also it shits on water spray, and you don't need much of it. If you hold the button for 3 secconds twice at a time in literally freezez the intercooler and this last for a bit. Anyway, you would only use it during a race or when you get bad heatsoak in traffic for example...There is no point having it on while you have plenty of airflow if you allready chilled the cooler....And waterspary is good for what it costs but can not lower the temp bellow ambient...

[30psi 4agte]

id been keen to see the results.

Mabe do all your tune runs and when your happy with them try thr co2 to see the difference it makes?

[BLK1g-gte]

Yeah that is the plan. Do all the tuning, with fuel, ignition and usual and then test the Cry02 and see the diffrence. I am doing this with a few parts atm for the 1G fellas. I am just stuck at the moment putting in the cams and hopeing if time permits to get it on a dyno in a next week or so. But Yeah i will post results in this tread...

[BeRad]

Xtreme at northgate will fill it, they fill n20 also, its not in VIC but surely theres someone down there.

Although it will be good to see some real results from it.

I am thinking in order of power producing ability it would go like this

1. nitrous
2. cry02
3. water/meth injection

I am fairly certain about nitrous being the highest but not too sure about the next 2. cry02 obviously can bring your intake temps down a lot but water injection can also do this and to fill it up it is free.

I hear what blk 1g-gte is saying re cooling temps and spool up off the line but I also wonder if water/meth injection would do the same. Maybe not to the same degree? I am positive that nitrous will help A LOT with spoolup!

Another thing to consider if it is for drags is that condensation droplets can lead you to be booted off the track as they are very strict on not letting any fluids on the track. Unsure if this happens with cry02 but it shouldn't happen with n2o or water/meth.

Gains on a dyno are good for wank factor though

Either way, there is definitely more than one way to skin a cat in this circumstance. I personally think for street use water/meth injection is best as it is easily concealable, cheap to top up etc. Nitrous is best for the drags if you want to use it as from my limited experience I was seriously impressed! cry02 is an unknown for me at present. Unsure if is legal for the street. Can't imagine the popo would be too happy to see a bit bottle in the boot with no mod plates. I am sure it will improve power but how much is the question. Would also be interesting to see how much additional timing can be run with cry02 compared to water/meth injection which I know helps a lot in this regard.

my 10c, my 2c is free.

[BLK1g-gte]

Water injections is a different cattle of fish comparing to waterspray. From what i know i think water/meth injection will work better then the cry02 cause you can run more timing/boost. But like i said will wait till dyno and post results. Legality wise, its debatable as cars come with a standard co2 fire extinguisher these days in the boot..this is just a bigger bottle

Xtreme at northgate will fill it, they fill n20 also, its not in VIC but surely theres someone down there.

Although it will be good to see some real results from it.

This is exectly the joint i need cause the company recomended a N20 filling station as it fills more of the liquid of co2. Anyone know a join in Victoria.
